Maxim ICL7662CBD

РатиометрическийЗарядный насос4.5V20V

Overview

The Intersil ICL7662CBD is a monolithic high-voltage CMOS power supply circuit which offers unique performance advantages over previously available devices. The ICL7662CBD performs supply voltage conversion from positive to negative for an input range of +4.5V to +20.0V, resulting in complementary output voltages of -4.5V to -20V. Only 2 noncritical external capacitors are needed for the charge pump and charge reservoir functions. The ICL7662CBD can also function as a voltage doubler, and will generate output voltages up to +38.6V with a +20V input.

• No External Diode Needed Over Entire Temperature Range• Pin Compatible With ICL7660• Simple Conversion of +15V Supply to -15V Supply• Simple Voltage Multiplication (VOUT = (-)nVIN)• 99.9% Typical Open Circuit Voltage Conversion Efficiency• 96% Typical Power Efficiency• Wide Operating Voltage Range 4.5V to 20.0V• Easy to Use - Requires Only 2 External Non-Critical Passive Components• Pb-Free Plus Anneal Available (RoHS Compliant)
